To rlZZ 'fe/0m it may concern:

Ile it known that I, I'IILLARD A. MCCOY, a citizen of the United States,and a resident of lerth Amboy, in the county of'Middlesex and State ofNew Jersey, have invented a new and Improved Corrugated-Iron Fastener.of vchichthe following is a full, clear, and exact description. v

rI'his invention relates to improvements in fastening devicesforvcorrugated ,sheet metal, and has for an object to provide animproved structure which may be quickly applied and removed.

Another object of the invention is-to provide a simple. strong fasteningdevice in which a minimum number of parts are used without sacrificingany of the strength or retaining ability of the device..

In carrying out the object of the invention a substantially Z-shaped baris provided, one end of which is designed to be placed against thesupporting angle bar or other support and the opposite end is adapted toengage one of the corrugations of a sheet lof, corrugated metal. A boltis then passed through the corrugation and through the end of theZ-shaped bar,after which a nut is screwed in place. The bolt ispreferably formed with an arc-shaped head so as to properly fit thecurve of the corrugation and to prevent a turning of the bolt when thenut is tightened.

In the accon'ipanyiug drawings-Figure 1 is a perspective view of anembodiment of the invention, the same being shown connected with part ofa roof; Fig. 2 is a section through Fig. 1 approximately on .line 2*:2;Fig. 3 is a section through Fig. 2 on line 3 3; Fig. lis a transversesection through a slightly modified form of the clamping bar. Fig. 5 isa sidevievv of the structure shown in Fig. 4.

Ileferring to the accompanying drawings by numeral 1 indicates an angleiron support and 2 a piece of sheet metal designed to be supported bysupport 1 in the usual manner in which a sheet metal roof is supported.Engaging the angle iron 1 is a fastening or clamping bar 3 formedsubstantially Z-shaped so that end 4 may press against angle iron 1 andend 5 may engage one of the eorrugations of-the sheet metal covering 2.

As clearly shown in Fig. 3 the end 5 is arranged so that the edges G and7 pinch the corrugation 8 'while head 9 of bolt 10 clamps tightlyagainst corrugation 8. Bolt 10 is designed to pass through corrugationand also through end 5. A. suitable nut 11. is provided for clamping end5 in position. In clamping end 5 in position end i is also. pressedagainst angle iron 1 so that the sheet metal 2 is lirmly clamped orsecured to the angle iron l. By using the bolt 1() the bar 3 may bequickly applied or if desired removed. rllhe arrangement of the head 9so as to conform to or fitl the corrugation 8 provides means by whichthe bolt will not turn when tightening nut 11.

In forming the clamping tool 3 so as to accommodate bolt 10 an aperture12 is provided, ivhich preferably extends lengthwise of the bolt, asshown in Figs. 1 and 2, tl'iough if desired it may extend transverselyor in anyA other desired direction. rIhis is very desirable as it allowsthe bar 3- to be applied quickly in close spaces or corners, and inaddition allows a certain amount of adjustment adapted to variousspaces.

Fig. L1 discloses a sectional View through a slightly modified form ofbar 3. This form of bar is formed arc-shaped at end 5 so as to fit intothe corrugated metal 2 and thus alloiv the nut 11 to clamp more firmlyagainst thesheet metal without bending the same.

In the construction of a roof any desired number of the bars 3 may beused, and it will be evident that these bars could be adapted to notonly the angle iron 1 but to any form of supporting bar. By reason ofthe fact that the bars 3 clamp the support ing angle iron 1, vibration,expansion and;

contraction are permitted without damage to any of the material and yetthe roof is held properly in place.

. Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is- 1. In a fastener of the class described,the combination with a supporting bar and a sheet metal coveringsupported by said bar, of a retaining and clamping bar formedsubstantially'in the shape of an ogee curve with the ends substantiallystraight, one end heilig formed on its upper surface so as to conformsubstantially to the shape of said supporting bar and the other endbeing provided -ivith a slot, and a `clamping bolt vextending throughsaid lslot and through @said sheet lnetal for clamping the sheet -metalto said slotted end and the clamping bar against said supporting bar,said clampngbolt being provided with a heed conforming substantially tothe shape of the sheet metal, and aclamping member pressing against theclamping bar.

2. In a fastening for sheet metal, the combination with a supporting barand a sheet metal covering supported by said bar, of a clamping barformed with a pair of end.

portions extending in opposite directionslin parallel planes andconnected by a diagonal portion, and a clamping bolt provided withMILLARD A. MCCOY.
